A Staunton set where the Rook is taller than the Knight is uncommon. Do you know of many others besides the HoS Collector Series? Looking at it now, it doesn't bother me at all. I kinda like it.
It looks like HoS "fixed" this with the follow-up Collector II Series. I actually prefer the first one with the taller Rook.

I learned chess using my uncle's Windsor Castle chess pieces. So I prefer sets with rooks slightly taller than knights.
I only have seen where the knight is shorter than the rook in BCC popular sets. I also prefer the knights taller than the rooks yes.
The set was purchased in 2012, boxwood / rosewood Collector Series, 3 inch King -I have a nice wooden box with the set info on the bottom. I also have a Collector set with ebony dark pieces and those rooks are shorter than the knights. . . . Maybe I bought that one at a different time, I really don't remember. I've been using the rosewood set, but I think I'm going to put it away in favor of the ebony, I like the shorter rooks . . .
The Chessbazaar Richard Whitty chess pieces are one of my 3 favorite sets. They all have large, tall rooks. The king is 3.75", the rook is a tall 2.7" ,, the knight is 2.5" tall. I use a board with 2" squares. The rook was the most powerfull piece for more than a thousand years. It still is the second most powerfull piece. I like tall, robust rooks . I dislike short, small rooks . The size of the piece should be determined by it,s relative strength.
In 1900, the British Chess Company issued their last two designs, a reissue of the Imperial Chessmen and the Improved Royal Chessmen. One of the distinguishing features of the latter was that they turned away from the customary approach of making the pieces linearly smaller starting from the king. The British Chess Company rather pursued the approach of aligning the size of the pieces with their playing value, which led to a clear enlargement of the rooks to signal their higher playing value compared to the knights and bishops.
Am I the only one who HATES when the rook is taller than the knight? I have a Collector set, actually more than one, from HOS and I really like the shapes, except for the height issue . . .
